I've got about 20 sites all different domains and IP's, all unique useful content. Basically the 20 sites all point to one main site (that doesn't point back) and the interior pages of the main site (that don't point back). Last night they all vanished.
Why did this happen is the question?
First off. I made these sites about 2 years ago and interlinked each and every one *Back then you could get away with it* About a year ago I made sure they were all squeaky clean. Only linking to another when useful to visitors. I was real careful. However there were a few highly competitive keywords that I went after so I did interlink a few sites. I wouldn't say it was heavy interlinking, but a good amount. They were relevent to each other so I thought what the hell. I've had excellent rankings up until last night in yahoo.
I have a feeling yahoo saw all my sites that were pointing to my main site and the interlinking and decided to ban the whole ip c block. Cause everything on the block is gone. Even sites that are totally separate.
Also I have a theory that yahoo lets their site match participants get away with alot more while the free listings get highly scrutinized. Makes sense for them, but sucks for anyone that doesn't pay.
Anyone have any experience with something link this?
Since then and thanks to everyone at these forums I've changed by thinking and am more focused on one large site with useful content and relevent links on ONE domain. It's so much easier. These old sites get a ton of traffic though so I can't just leave them.
